Introduction

The Dynisco model PT375 flush diaphragm pressure transducer

is designed to measure from 0 Ð 1000 psi up to 0 - 30,000 psi.

This model incorporates a 350-ohm, bonded foil strain gage

Wheatstone Bridge. This proven technology provides an

voltage output proportional to pressure (within the specified

error band). These transducers convert changes in applied

pressure into corresponding changes in voltage signals. These

output signals can be fed into a wide range of measurement

instrumentation with millivolt capability.

Pressure Fitting

The pressure fitting on the PT375 flush diaphragm pressure

transducer is a 3/4"-16 UNF-2A thread. The sealing surfaces

the 60û cone near the diaphragm, excluding the threads from

the wetted area.

The recommended mounting torque is:

50 ft-lbs.: Ranges ³ 20,000 psi

100 ft-lbs.: Ranges = 30,000 psi

Wiring

All PT375’s are equipped with a 6-pin, Bendix PT1H-

10-6P (or equal) receptacle. The suggested mating plug

is a Bendix PT06W-10-6S or equivalent, Dynisco P/N

711610. The PT375-0 has a six conductor integral

cable.

Internal Shunt Calibration

Each transducer includes an internal shunt calibration

("R-Cal") function that is used to simulate a signal of 80%

full scale, this is achieved by crossing pins E and F. This

eliminates the need for cumbersome calibrated pressure

source when scaling associated instrumentation.
